DEVICE FOR ATTACHING BUTTONS TO GARMENTS.

SPECIFICATION forming part of Letters Patent No. 243,303, dated June 21,1881.

Application tiled March 11,1881. (No model.)

To all whom it may concern Y Be itknown that. I, CLARK M. PLATT, ofVaterbury, in the county of New Haven and State of Connecticut, haveinvented a new and Improved Anvil for Attaching Buttons to Garments; andI do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making part of this specification.

This invention is in the nature ofan improvement in a device forsett-ing the metallic rivets or shanks of buttons; and the inventionconsists in an anvil forsetting the metallic shanks or rivets ofbuttons, provided with jaws, in combination with a spring, the jawsbeing of cam shape, and constructed to have vertical and lateral play,as is more particularly hereinafter described.

In the accompanying sheetofdrawings, Figure l represents a plan or topview of my im'- proved anvil Fig. 2, a front view of same, partly insection; Fig. 3, a side vieu` of same; Fig. 4, a side view of my anvil,with jaws and spring removed; Fig. 5, a vertical section of same throughlinea? Fig. l Figs. 6 and 7, front view and vertical section throughline y y, Fig. 9, of modified anvil, with spring passing throughinterior of anvil; Figs. Sand 9, side and top views of same.

Similar letters of reference indicate like parts in the several figures.

In securing buttons with metallic fastening Shanks or rivets togarments, it is essential that the head of the rivet or eyelet should besupported iirmly onan anvil while its other end is upset within thebutton, which operation is more particularly described in reissuedLetters Patent granted to G. J.I Gapewell, February 23, 1869, N o. 3,3075 but in order to hold the rivet in place on the anvil itis necessarythat some yielding device, such as elastic jaws, should be employed, sothat while the rivet may be held to the anvil durin g theriveting'process it may also be readily detached from the anvil and jawsafter the riveting is completed and the button is fastened to thegarment. Heretofore this releasing has been done by hand by slipping therivethead from between the jaws. By my invention, however, the releasingof the rivet-head is automatically accomplished, and much time thereforesaved.

To that end I construct my anvil A with recesses a on two of its sides,with jawsB tted within the same. These jaws have cam-shaped upper ends,b, which overlap to some extent the upper surface of the anvil, as shownin Figs. 1, 2, 6, 7, and 9. Fitted in a groove, c, and surrounding theanvil and the sides ofthe jaws B, is a spring, C, of sufficientelasticity to confine the sides of the jaws B snugly in contact with therecesses a and sides of the anvil, in which position the overlappingends resting firmly upon the upper surface of the anvil A. A needle suchas is ordinarily used for passing tubular rivets into garments is placedwithin the rivetor eyelet, the garment h forced over the needle and theshank of the eyelet until the shank protrudes through the garment. Thebutton 7c is next placed over the end ot' this protruding shank, and upto this time theelastic force of the overlapping jaws B has held therivet firmly in position and tightly against the anvil. Thesettingplunger l now descending upon the face of the button, the tubularend of the rivet or eyelet, by reason of the cone on the endof theplunger and the depression in the face of the button, is split or spreadwithin the button-shell, uniting the two iirmly together 5 but as theplunger descendsto accomplish this riveting it at the same time forcesthe garment firmly against the upper and projecting surfaces of theoverlapping jaws B, forcing these jaws downward, which operation ispermitted by the elliptical openings e, and as these jaws are in thisway forced down the cam or curved shape b of the jaws causes the jaws tospread outward sufciently to release the rivet-head from their grasp, sothat the rivet is instantly and automatically removed from the anvil tomake room for another, to be proceeded with as before, the jaws beingrestored to their' normal position, after releasing the rivetg by theelastic force of the spring C acting against the shoulders o of thejaws.

By constructing the jaws so that they may have a yielding verticalmovement they cannot punch a hole in the garment when the plungerdescends to clinch the rivet, nor will they be broken, as is the casewith jaws imrnovably xed to the anvil 5 besides, by their elasticity,the rivet-heads are more readily inserted by the operator between thejaws without the danger of cutting the lingers, as in anvils withstationary jaws.

Instead of employing a surrounding` spring, C, as shown in Figs. l, 2,and 3, and as above described, a spiral or elastic spring may beinserted through an. opening in the body ot' the anvil and connected tothe jaws in any desirin combination with a spring, substantially as andfor the purpose described.

2. In an anvil for upsetting rivets and eyelets, studs xed to the sidesthereof, in combination with jaws having overlapping ends and ellipticalopenings in thelegs of the same, whereby vertical and lateral movementis secured, substantially as and for the purpose described.
